Line Charge Assembly and System for Use in Shallow-Water Clearing Operations
Abstract
A line charge assembly and system are provided for use in a shallow-water obstruction clearing operation. Each assembly has a propulsion unit capable of flight through the air, a line charge array, an air-safed water-armed fuze, a first interrupter disposed between the line charge array and the fuze, and a second interrupter disposed in the line charge array. The line charge array is defined by a plurality of line charges successively coupled to one another by a detonation line capable of transferring detonation energy therealong successively to each line charge. The line charge array has a first end coupled to the propulsion unit and has a second end coupled to the first interrupter. The fuze generates the detonation energy at the expiration of a first time period provided the fuse is in water. The first interrupter permits the detonation energy to be transferred from the fuze to the second end of the line charge array until the expiration of a second time period. The second interrupter permits the detonation energy to be transferred therethrough until the expiration of a third time period. The first time period expires before the expiration of the second and third time periods. The first interrupter operates independently of the fuze to essentially sterilize a dud fuze. The second interrupter operates independently of the fuze and first interrupter to prevent the back propagation of sympathetic detonation energy to any of the assembly's line charges that reside between it's fuze and the first interrupter in the case where the fuze is a dud.
